A few months have passed since I got married and started living in my husband's parents' house. I was nervous at first, but thanks to my kind father-in-law, I now feel at home. However, there is one strange thing. My father-in-law's room on the back of the second floor had a strange atmosphere, as if I was telling him not to go near it. One day, I came back home earlier than planned, but I heard a faint groan coming from my father-in-law's room on the second floor.
